DMF solution of AESO-AZ (20%) and a corresponding DMF solution of polyacid (20%) were mixed in vials for 10 min. The mixture was then poured into a Teflon mold (5 in×5 in) and dried at ambient temperature. The mold was placed in an oven at 60° C. for 24 h. The obtained films were transparent, indicating the amorphous nature of the polymer network. The reaction is shown in Scheme 2.

Example 3. Characterization

The aziridine content of AESO-AZ was determined according to the titration method published by Jay R R: Direct Titration of Epoxy Compounds+Aziridines. Anal Chem 1964, 36(3):667. Approximately 0.5 g (precisely weighed) of the sample was dissolved in 15 mL chloroform, then 15.00 mL 10% chloroform solution of tetrabutylammonium iodide together with 2 to 3 drops of crystal violet indicator were added. The mixture was titrated with 0.1 N HClO₄. A blank sample was used to eliminate background effects. This titration method is also applicable to epoxy groups; therefore. AESO was titrated as well since it contains some residual epoxy groups resulting from the manufacturing process (acrylation of epoxidized soybean oil). ¹H NMR spectra of AESO and AESO-AZ were recorded on a Varian spectrometer (Palo Alto, Calif.) at 300 MHz in chloroform-d. The average molecular weight of AESO and AESO-AZ were determined by a Thermo Scientific Dionex Ultimate 3000 GPC (Sunnyvale, Calif.) equipped with a Shodex Refractive Index (RI) at room temperature. Tetrahydrofuran (THF) was used as eluent solvent and the delivery speed was 1.0 mL/min. The viscosity of AESO-AZ was measured by varying the shear rate from 10 s⁻¹ to 1000 s⁻¹ on an AR2000 Rheometer (TA Instrument).

The gel content was measured via Soxhlet extraction. A known weight (W₀) of pre-conditioned sample was placed in the Soxhlet extractor with continuous THF extraction for 1 d. The remaining sample was dried and weighed as W₁. Three tests were performed for each sample. The gel content % was calculated as (W₁/W₀)×100%.

Differential scanning calorimetry (DSC) was performed on a TA Instrument Q20. Samples were heated to 100° C. in the first ramp in order to eliminate their heat history. The samples were then cooled down to −50° C. and heated to 100° C. at a rate of 10° C./min. The heat profile of the second heating ramp was recorded and the glass transition temperature was determined using the midpoint inflection method.

A DMA Q800 (TA Instruments) was implemented to record the dynamic thermal mechanical behavior of the samples. Film-tension mode of 1 Hz was used for testing rectangular samples with a dimension of 15 mm×10 mm. The samples were kept isothermally for 3 min at −80° C. followed by a temperature rise to 120° C. at a programmed rate of 3° C./min. Tan δ was calculated as the loss modulus divided by the storage modulus and the glass transition temperatures (T_(g)s) were determined by the peaks of the tan δ curves.

Thermogravimetric analysis (TGA) of the films was conducted on a TA Instrument Q50 (New Castle, Del.). At a constant air flow rate of 60 mL/min. the samples were heated from ambient temperature to 650° C. at a rate of 20 OC/min. The decomposition profile was recorded as a function of temperature.

The tensile profiles of the samples were determined using an Instron universal testing machine (model 4502). Rectangular samples of 50 mm×10 mm were subjected to tension at a crosshead speed of 100 mm/min. The tests were replicated at least three times for each sample and the average of the reported values was determined. Toughness was calculated by integrating the area beneath the stress-strain curve.

Example 4. Results and Discussion. Preparation and Properties of AESO-AZ

Michael addition of 2-methylaziridine to acrylic groups on AESO was used to prepare AESO-AZ. An excess amount of 2-methylaziridine was added and the unreacted residual was removed via roto-evaporation, an approach possible because of the low boiling point of 2-methylaziridine (b.p. 66-67° C.). FTIR spectra of AESO and ASEO-AZ are shown in FIG. 1. The disappearance of the peak at 1635 cm⁻¹ (blue box) indicated the complete conjugate addition to the acrylic groups. The peak at 3053 cm⁻¹ was attributed to the C—H stretching on the aziridine ring. The peaks at 2930 cm⁻¹ and 2850 cm⁻¹ (C—H stretching in fatty acid chains) and at 1750 cm⁻¹ (C═O stretching of ester groups) remained unchanged after the reaction, indicating that the triglyceride structure of AESO was preserved.

The ¹H-NMR spectra in FIG. 2 also confirmed the completion of this reaction. Peaks d, e, f, corresponding to the hydrogen atoms on the acrylic group, disappeared after the reaction, which indicated the occurrence of a Michael addition. Peaks g and h in AESO-AZ were attributed to methylene protons that established that the acrylics were saturated after Michael addition. The three hydrogen atoms on the aziridine ring structure could not be clearly observed, but peak i, corresponding to the methyl group of 2-methylaziridine, established that 2-methylaziridine was the nucleophile in the Michael reaction. That the aziridine ring remained intact during the reaction was hard to prove by NMR, but the success of the subsequent polymerization with polyacids provided strong evidence that the aziridine ring was indeed intact. Peaks a, b, and c, associated with the hydrogen atoms labeled on the embedded structure, remained throughout the reaction, further confirming the preservation of the basic structure of AESO.

¹³C-NMR spectra were obtained for AESO and AESO-AZ. In FIG. 3, the disappearance of peaks a and b and the appearance of peaks c and d illustrated the fact that the acrylic groups of AESO underwent Michael addition with the —NH-bridges of the 2-methylaziridine.

The viscosities of AESO and AESO-AZ at room temperature and the molecular weights M_(n) and M_(w) are summarized in Table 1. There was no distinct difference in viscosity between the two specimens, indicating that the intermolecular interactions were not remarkably changed after the reaction. The molecular weight of AESO-AZ was slightly higher than that of AESO because of the addition of 2-methylaziridine.

TABLE 1 Properties of AESO and AESO-AZ. Viscosity (Pa · s) at M_(n) M_(w) PDI AESO 27.3 1967 2165 1.10 AESO-AZ 29.9 2492 2665 1.07

Titration of the aziridine content was critical in order to determine the amount of polyacids required for the polymerization step, because the molar ratio of aziridine and carboxylic acid has to be 1:1. This titration method is also applicable to epoxy. Upon titration, AESO had an epoxy content of 5.55×10⁻⁵ mol/g. Assuming that there was no change in epoxy content after Michael addition, the epoxy content was subtracted from AESO-AZ to get a net content of aziridine. AESO-AZ had an aziridine content of 0.00413 mol/g.

Example 5. Results and Discussion. Polymer Properties

Differential scanning calorimetry (DSC) was used to determine the thermal transitions of the polymeric materials and the DSC thermograms of the samples are shown in FIG. 4. Each sample exhibited only one T_(g), indicating a homogenous structure. In addition, no melting was observed, so all samples were determined to be amorphous. Notice that the polymer derived from succinic acid and AESO-AZ (succinic-AZ) exhibited the lowest T_(g) at 12.0° C. When succinic acid was replaced by citric acid (citric-AZ) or the isosorbide-based diacid (iso-AZ), the T_(g) of the respective polymer increased to 20.3° C. and 20.8° C. The increase in T_(g) of citric-AZ was attributed to a higher crosslinking density. Because citric acid had a functionality of 3, while the functionality of succinic acid was 2, the formation of more crosslinking sites in citric-AZ was expected, resulting in a higher crosslinking density. For iso-AZ, the presence of hard segments contributed to the increased T_(g). The rigid ring structure introduced by isosorbide remained during polymerization and may have restricted the motion of the polymer chains. The increase in functionality of the citric acid monomer in citric-AZ and the addition of hard segments in iso-AZ had similar effects on T_(g).

FIG. 5 shows the storage modulus (E′) and the loss factor (tan δ) as functions of temperature. In the low temperature regime, all samples were in a glassy state so that the storage modulus was relatively high because of the low mobility of the polymer chains. In addition, E′ dropped slightly before the temperature reached the material's glass transition point at which point the polymer chains were activated. The T_(g)s obtained by DMA were defined by the peak of tan δ. Only one tan δ was observed for each material, indicating the homogeneity of all investigated samples. The T_(g)s of succinic-AZ, citric-AZ, iso-AZ were 32.6° C., 39.7° C., and 38.9° C. respectively. It is worth mentioning that the discrepancy between T_(g) values obtained by DSC and by DMA is a commonly observed phenomenon caused by the different measuring mechanisms. While DSC measures the heat capacity change from frozen to unfrozen chains, DMA measures the change in mechanical response of the polymer chains to heating. As the temperatures passed the glass transition point, all samples entered into the rubbery state and E′ exhibited less dependence on temperature. A rubbery plateau was observed, strongly indicating the presence of a crosslinked network. The value of E′ at T_(g)+50° C. can be used to determine the crosslinking density (ν_(e)), where E′=3ν_(e)RT, where R is the universal gas constant, and T is the absolute temperature. The calculated crosslinking density for succinic-AZ, citric-AZ, iso-AZ were 287.4 mol/m³, 468.5 mol/m³, and 107.4 mol/m³, respectively, see Table 2. In addition, the height of tan δ decreased with increasing crosslinking density, matching the calculated results. The difference in crosslinking density between citric-AZ and succinic-AZ was caused by the difference in functionality (3 vs. 2). The higher functionality created more crosslinking sites, creating a denser network. Although isosorbide-based diacid has the same functionality as succinic acid, iso-AZ exhibited a lower crosslinking density than succinic-AZ, which was attributed to the presence of the rigid isosorbide ring interrupting the crosslinking network. In addition, the rigid ring in isosorbide-based diacid may have restricted the compactness of the network.

The gel content of all samples was close to or higher than 90% (see Table 2), indicating the presence of a highly crosslinked polymer network in each sample. The thermosetting behavior of the samples also confirmed successful polymerization.

The thermal resistance of the samples was investigated by TGA, see FIG. 6. All samples underwent three stages of thermal decomposition in air atmosphere. The first weight loss occurred between 100 and 350° C. and was assigned to the dissociation of labile bonds, such as ester groups and secondary amine groups. Succinic-AZ and citric-AZ exhibited similar decomposition profiles, because they were derived from similar, small aliphatic polyacids and differed only in functionality. Decomposition onset of iso-AZ occurred at lower temperatures and was attributed to the instability of isosorbide-based diacid, which underwent ester group dissociation at temperatures above 100° C. The second thermal degradation stage between 350 and 450° C. was attributed to chain scission in the soybean oil structure. The last stage, above 450° C. was caused by further thermo-oxidation of the samples due to the presence of oxygen in air atmosphere. The temperatures of 10% and 50% weight loss, T₁₀ and T₅₀ respectively, are summarized in Table 2. Iso-AZ exhibited the lowest T₁₀ because of the low thermal resistance of the ester bond attached to the isosorbide ring. The T₅₀s for all samples were similar as these temperatures reached the regime of chain scission for the triglyceride structures.

Tensile profiles for all samples are plotted in FIG. 7. Young's moduli tensile strength at break, elongation at break, and toughness are summarized in Table 3. Citric-AZ and iso-AZ were stiffer and stronger compared to succinic-AZ. The relatively higher crosslinking density of citric-AZ provided better resistance to deformation and thus resulted in higher Young's modulus than succinic-AZ. The low crosslinking density of iso-AZ was compensated by the presence of the rigid ring. Succinic-AZ exhibited the highest ductility of all samples, following a common rule that weaker materials exhibit higher ductility. All samples showed comparable toughness.

Example 6. Results and Discussion. Conclusions

Successful Michael addition under mild reaction conditions resulted in the grafting of 2-methyl aziridine onto acrylated epoxidized soybean oil, and the azidirine content was titrated as 0.00413 mol/g. The clean and complete incorporation of 2-methylaziridine into the product was confirmed by FTIR, ¹H-NMR and ¹³C-NMR. Multiaziridine-containing acrylated epoxidized soybean oil (AESO-AZ) was then subjected to rapid room-temperature polymerization with succinic acid, citric acid, and an isosorbide-based diacid, respectively. The polyacids were added to AESO-AZ at stoichiometric ratios. Polymeric materials were successfully obtained. The process took place rapidly and films were obtained by evaporation of the solvents. Differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), thermogravimetric analysis (TGA), and tensile stress-strain tests were performed. Generally, the glass transition temperatures of citric-AZ and iso-AZ were higher than that of succinic-AZ, which was attributed to a difference in functionality of the respective acids. Citric acid has a functionality of 3, while succinic acid has a functionality of 2. High functionality results in higher crosslinking density, which contributes to the higher T_(g). Though isosorbide-based diacid has the same functionality as succinic acid, the presence of a rigid ring derived from isosorbide increased the T_(g). The higher Young's moduli and higher tensile strength of citric-AZ and iso-AZ were attributed to the same effect. Succinic-AZ was the most ductile polymeric material, resulting from the highest mobility of its polymer chains. The glass transition temperatures (T_(g)) of the samples suggested that increased functionality of the carboxylic acid groups in the polyacids may have effectively increased T_(g), while the rigid rings in isosorbide did not have significant impact on T_(g).
